Thread: Help needed please.

The program returns many errors and I've tried for 2 days to figure out the problems I '//' commented out the addRecord and enterRecordDetails and the program worked. I had written those functions in other programs.

Code:

#include "seatbooking.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>


int validateSectionLetter(char c)
{
	
	if ((!isalpha(c)) || (c == 'Z') || (c == 'z'))
	{
		printf("\n** You entered an invalid section. Please enter a section from A to Y. **\n\n");	
		return 0;
	}
	
	return c;
}


char enterSectionLetter()
{
	char  c = 0;
	
	do
	{
		printf("Enter Section [A - Y]: ");
		c = getchar();
		while (getchar() != '\n');   
	}
	
	while(!validateSectionLetter(c));
	return c;	
} 


void printGrid(int grid[][GRID_HEIGHT])
{
	int x, y;


	printf("\n\n | ");
	for (x = 0; x < GRID_WIDTH; x++)
	{
		printf("%d ", x+1);
	}
	printf("\n");


	printf("==");
	
	for (x = 0; x < GRID_WIDTH; x++)
	{
		printf("==");
	}
	printf("\n");	


	for (y = 0; y < GRID_HEIGHT; y++)
	{
		printf("%c| ", y + 'A');
	
		for (x = 0; x < GRID_WIDTH; x++)
			{
				printf("_ ");	
			}
		printf("\n");	
	}
	printf("\n");
	
}


// enter seat detail
void enterRecordDetails(User *user)
        {
        printf("Enter name: ");
        scanf("%s", user->name);
        printf("Enter surname: ");
        scanf("%s", user->surname);
        printf("Enter CountryCode: ");
        scanf("%s", user->country);
        printf("Enter Passport: ");
        scanf("%s", user->passport);
        }


// add record
int addRecord(const char *filename, const User *studentRecord)
{
        FILE *file = fopen(filename, "ab");
        if (file == NULL)
        {
               printf("Error opening file %s.\n", filename);
               return 0;
        }


        fwrite(studentRecord, sizeof(User), 1, file);
        fclose(file);
        printf("Record saved to %s\n", filename);
        return 1;
}


		
int validateMenuChoice(int choice)
{
	if ((choice < 1) || (choice > 4))
	{
		printf("** You entered a invalid choice. Please choose an option from 1 to 4. ** \n\n");
		return 0;
	}
	return 1;
}


int menu()
{
	int choice = 0;


	do
	{
		printf("** Olympics 2012 Seat Booking System **\n\n\n");
		
		printf("1. Show Bookings\n");
		printf("2. Book a seat\n");
		printf("3. Display country stats\n");
		printf("4. Exit\n");
		


		printf("\nEnter Choice: ");
		scanf("%d", &choice);
	}
	while (!validateMenuChoice(choice));


	return choice;
}


int main()
{
	int choice = 0;
	int grid[GRID_HEIGHT][GRID_WIDTH] = {0};
	choice = menu();
	User user = {0};


	char row; 
    char section = 'a';
    int col;
    
	
	switch (choice)
	{
	case 1:
		break;
	case 2:
		enterSectionLetter();
		printGrid(grid);
		
		printf("\nEnter Row [A - J]: ");
        scanf("%c",&row);
        printf("\nEnter Seat Column Number [1 - 9]: ");
        scanf("%d",&col);
        
        enterRecordDetails(&user);
        addRecord(FILENAME, &user);
		break;
	case 3:
		break;
	}
}

This is the structure in the header file:

Code:

typedef struct User
{
        char name[25];
        char surname[25];
        char country[3];
        char passport[10];
}User;

I had use those functions in a similar program and no errors were given by the compiler. I am using Visual Studio Professional.

Ok thank you a lot for your time
I'll try and fix the errors and let you know
